The recent solar eclipse was a powerful experience. Whether you traveled hundreds of miles to see the totality, or just popped outside on your lunch break to share a pair of eclipse glasses with a friend, you experienced a beautiful astronomical and social moment. You might be feeling a strong connection, intellectually or spiritually, with the sun and the moon right now. But that connection does not reach your uterus.

These articles rely on anecdotes—a handful of women saying their periods have been weird the last few weeks—and invoke astrological and mystical energies. At least the Teen Vogue article was categorized under spirituality. Because, physiologically, there is nothing going on here.

Sure, the moon affects the tides. And yes, the moon’s 28-day orbit may match up with some people’s menstrual cycles. But that doesn’t mean the moon’s pull is felt by the uterus’s lining. And even if it were—which it is not—the precise visual alignment of the sun and the moon isn’t significantly different from a standard “spring” tide, where the moon and the sun are on the same side of the Earth.

The eclipse was an awesome event that united millions of people around an astronomical phenomenon. There’s plenty of actual science there. And if your period is really weird this week, maybe see a doctor.
